Polymerization reaction engineering
PRE(Polymerization reaction engineering) studies the different ways polymerization reactions work and how to influence them in order to achieve desirable results. The field is very broad, but I have been focusing on miniemulsion polymerization, which is a technique to produce very small polymeric particles (nanometric) that encapsulate a certain product. These particles will then slowly degenerate, releasing the product over time. This type of particles find a great range of applications in the medical/pharmaceutical field, with the possibility of medicines or supplements to be encapsulated and then released over a long span of time, without the necessity of re-injection of more of the substance.
Abstract: The present invention concerns a method for preparing a polymer comprising a step (EI) for dispersed phase polymerization in the presence of a reactive stabiliser, wherein the following are brought into contact in an aqueous phase:—at least one ethylenically unsaturated monomer; —at least one source of free radicals; and—a reactive stabiliser comprising a polymer chain including monomer units (N-vinyl lactam) and a thiocarbonylthio-S group (C═S)—.

Abstract: Disclosed is a method for producing vinyl ester urethane resins, in which a dianhydrohexitol-compound is reacted with a diisocyanate in the presence of a monomeric radically co-polymerizable compound as a solvent and the product is reacted with a hydroxy-substituted (meth)acrylate. As a result, vinyl ester urethane resins based on dianhydrohexitol-compounds and also based on renewable raw materials can be obtained in a simple manner with high yields. The resins are suitable as binding agents in chemical fixing engineering.

Abstract: A method of repairing damaged cartilage and soft tissue in a patient is provided using a biocompatible, non-immunogenic composition. The composition comprises a hydrophilic polymer and a plurality of crosslinkable components having reactive functional groups. The composition used in the method may be loaded with biologically active agents for delivery to the damaged tissues. Kits for use in carrying out the method of the invention are also provided.
